on the idea of candidates staying in, the republican media strategist for mitch daniels of indiana told me tonight if i were mitt romney i would be sending flowers to newt gingrich and say, please stay in, because you're going to prevent rick santorum from knocking me off. >> if you get any word of any communication between rick santorum and mitt romney, call us first. i feel like we all have eyes on that dynamic. >> what i'm hearing from the santorum campaign is trying to -- in their own way, ratchet up pressure on gingrich to get out, just in the way that the romney campaign would like santorum to get out. basically saying, newt gingrich needed to win second almost every place, and he's not going to do that, in addition to winning georgia. there isn't a path for newt gingrich to win the nomination, but newt gingrich is operating on his own clock, his own decision making, ego, ambition, his long term goal as a politician and as somebody in the private sector. not easy to see exactly what is going to make or who is going to make newt gingrich get out and make it easier for rick santorum
